,[''Motor Cycle News'' 14 March 2018] senior bike tester Michael Neeves wrote that the KTM "manages to combine the best bits of its rivals", with "the speed and electronic sophistication of the Triumph Street Triple R, the punch and simplicity of the MT-07 and the cheekiness of the MT-09 ... with a dash of crazy 1290 Super Duke R". Neeves praises the KTM's riding position and comfort, but points out that wind protection is non-existent. His overall verdict: "Its engine is a peach, the chassis balanced and it's topped off with superbike-spec electronics".
